HP MSR1003-8S Command Reference Manual page 14

-f: Sets the "do-not-fragment" bit in the IP header.
-h ttl: Specifies the TTL value of ICMP echo requests. The value range is 1 to 255, and the default is 255.
-i interface-type interface-number: Specifies the source interface for ICMP echo requests. If you do not
specify this option, the system uses the primary IP address of the matching route's egress interface as the
source interface for ICMP echo requests.
-m interval: Specifies the interval (in milliseconds) to send ICMP echo requests. The value range is 1 to
65535, and the default is 200.
-n: Disables domain name resolution for the host argument. If the host argument represents the host name
of the destination, and if this keyword is not specified, the device translates host into an address.
-p pad: Specifies the value of the pad field in an ICMP echo request, in hexadecimal format, 1 to 8 bits.
The pad argument is in the range of 0 to ffffffff. If the specified value is less than 8 bits, 0s are added in
front of the value to extend it to 8 bits. For example, if pad is configured as 0x2f, then the packets are
padded with 0x0000002f to make the total length of the packet meet the requirements of the device. By
default, the padded value starts from 0x01 up to 0xff, where another round starts again if necessary,
such as 0x010203...feff01....
-q: Displays only the summary statistics. If this keyword is not specified, the system displays all the ping
statistics.
-r: Records the addresses of the hops (up to 9) the ICMP echo requests passed. If this keyword is not
specified, the addresses of the hops that the ICMP echo requests passed are not recorded.
-s packet-size: Specifies the length (in bytes) of ICMP echo requests (excluding the IP packet header and
the ICMP packet header). The value range is 20 to 8100, and the default is 56.
-t timeout: Specifies the timeout time (in milliseconds) of an ICMP echo reply. The value range is 0 to
65535, and the default is 2000. If the source does not receive an ICMP echo reply within the timeout,
it considers the ICMP echo reply timed out.
-tos tos: Specifies the ToS value of ICMP echo requests. The value range is 0 to 255, and the default is
0.
-v: Displays non-ICMP echo reply packets. If this keyword is not specified, the system does not display
non-ICMP echo reply packets.
-topology topo-name: Specifies the topology to which the destination belongs, where topo-name is a
case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify this
option.
-vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the destination belongs,
where the vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination
is on the public network, do not specify this option.
host: Specifies the IP address or host name of the destination. The host name is a case-insensitive string
of 1 to 253 characters. It can contain letters, digits, and special characters such as hyphen (-), underscore
(_), and dot (.).
Usage guidelines
To use the name of the destination host to perform the ping operation, you must first configure the DNS
on the device. Otherwise, the ping operation will fail.
To abort the ping operation during the execution of the command, press Ctrl+C.
Examples
# Test whether the device with an IP address of 1.1.2.2 is reachable.
